Contribution of Arm and Leg Muscle Power to The Results of Swimming 50 Meter Breaststroke Swimming Siger Sembilan Swimming Lessons

This study aims to determine the contribution of arm and leg muscle power to the results of 50-meter breaststroke swimming in male athletes from Siger Sembilan Swimming Lessons. The method used is a quantitative descriptive method with a correlational approach. The research sample consisted of 40 people. The research instruments used included a two-hand medicine ball throw test to measure arm muscle power, a vertical jump test to measure leg muscle power and a 50-meter breaststroke swimming test using a stopwatch. The research hypothesis: 1) there is a contribution of arm muscle power to the 50-meter breaststroke swimming result, 2) there is a contribution of leg muscle power to the 50-meter breaststroke swimming result, 3) there is a contribution of arm and leg muscle power to the 50-meter breaststroke swimming result. The research results showed that: 1) there is a significant contribution of arm muscle power to the 50m breaststroke swimming (calculated r = 0.343 > table r = 0.320) with a contribution of 11.81%, 2) there is a significant contribution of leg muscle power to the 50m breaststroke swimming (calculated r = 0.556 > table r = 0.320) with a contribution of 30.94%, 3) Simultaneously, the contribution of arm muscle power and leg muscle power to the 50m breaststroke swimming (calculated r = 0.508 > table r = 0.320) with a contribution of 25.48%.
